See 75 of his favorite posters in Gotta Dance! The Art of the Dance Movie Poster. This First Thursday at Rediscovered Books (180 N. Eighth St.), he'll tell stories about the book, as well as share some original posters from his collection.

"My hope is that this event can launch his whole exhibit into a gallery space here in Boise," said Rediscovered Books co-owner Laura Delaney.

The presentation begins at 7 p.m. with a short video that shows professional dancers in New York City recreating the poses seen on the movie posters. Snacks and refreshments will be on hand from the Basque Market. The event is free and open to the public.
